Wow! I'd swear that the photo was photoshopped. It gave me a weird perception of the focal length...Blackout wrote: ↑22 Jan 2022, 08:18It's the 2014 engine. And those are apprentices ; )

the photo is the clearest in showing that one bank's runner was (is it still ??) longer than the other's
cancelling at best rpm the 90 deg V's 'phase lag' to keep even the exhaust pulse train - as I predicted c. 2014
no I haven't checked vs engine rotation etc
the later single turbo Renaults c.1978 also showed differences in runner length - then twin turbos eliminated this factor

Internet troll spreading a rumour that might wel could be true, but not based on actual rumours but on history about Renault and their reliability when doing sometin' new.Jambier wrote: ↑17 Feb 2022, 13:36What do you think about the Renault engine rumors ?
Not powerful, not reliable and struggle with E10
If that is true, given that they have done nothing on the engine side since very long, this is a serious issue... if after all those year they are not capable of having the good engine, they should stop their F1 program to be honnest
Where did you read this ? Last thing I heard was they were happy with power but still had some questionmarks on reliability.Jambier wrote: ↑17 Feb 2022, 13:36What do you think about the Renault engine rumors ?

That was just a Twitter troll twisting Prost’s words that described what you just said.
Former Alpine non-executive chairman Alain Prost said when he split with the team last month that the engine was having reliability problems on the test bed.
Rossi said the failures were caused by his asking the engine department to push as hard as possible for maximum performance. He said the design was now running reliably in time for the start of pre-season testing next week.
Rossi said: "I told the team: 'You push the envelope far. I don't care. I'd rather have to dial down the performance, but know that I've reached a peak of the performance I can get and then be reliable, than just feel comfortable with a reliable engine that was not delivering the performance.' Which, by the way, was the approach of the past.
"The good news is we've been doing thousands of kilometres with this new power-unit in the last few weeks, and it went just fine.
"So knock on wood it seems we have fixed that."
An all-new engine for 2022
Rossi said the changes at Alpine were aimed at bringing the team up to a level where it could compete at the front.
Part of that plan is the decision to design an entirely new engine to power drivers Fernando Alonso and Esteban Ocon this season.
The new power-unit follows the philosophy set by Mercedes at the start of the turbo-hybrid era in 2014, and since followed by Honda. It splits the turbo and compressor, two parts that in a conventional design sit next to each other, by putting the compressor at the front of the engine and the turbo at the back.
"The engine has been redesigned entirely," Rossi said. "The split turbo is one element. We will [also] make it more compact, which enables us to move it closer to the driver and therefore the centre of gravity of the car.
"It's lighter. It's capable of operating in a much wider range of conditions, temperature and pressure.
"So it's really like a game-changer for us and it's going to, I hope, enable us to catch up and close the gap to the front of the queue [on engine performance]."
The split-turbo design is difficult to achieve because it requires a long connecting rod between the turbo and compressor that runs across the top of the engine and spins at up to your 125,000rpm.
